CAR-AXLE LUBRICATOR.

SPECIFICATION forming part; of Letters Patent No. 357,835, dated February 15, 1887.

Application filed October 11, 1886. Serial No. 215,826. (No model.)

To all whom it may concern:

Be it known that we, CHRISTIAN H. KOCK, A'll-IOL B. llIACKLIN, MIoIIAnL MoDERMoTr, and WILLIAM D. OBRIEN, citizens of the United States, all residing at Chicago, in the county of Cook and State of Illinois,-have invented certain new and useful Improvements in Car-Axle Lubricators, of which the following is a specification.

Our invention relates to means for more thoroughly and economically supplying railroad-car axles with a lubricant by means of a conveyer-spool resting and revolving in the axle-box, and has for its object to present means whereby asbestus or other lubricantcarricr may be employed to fill the spool, and may be securely attached thereto, and other defects in former similar devices may be remedied. These objects we attain by the mechanism illustrated in the accompanying drawings, wherein- Figure 1 is a side elevation, with parts broken away, of a lubricating-spool and its carriage. Fig. 2 is a sectional view near one end of the carriage. Fig. 3 is a plan view of a spool in process of being filled. Fig. 4 is a perspective of the carriage-spring. Fig. 5 is a view of a spring-blank before the same is Shaped.

Like parts are indicated by the same letter in all the figures.

A A are the end bars of the carriage, each provided with a box, B, to support the axle of the spool, and each in turn supported on the doublecurved spring C. These springs may be stamped out of sheet metal, and subsequently have a flange, D, turned up on either side to form a socket to receive the end bar of the carriage. These flanges are perforated, as are also the side bars, to admit of the reception of a bolt, E, which thus securely at; taches the spring to the bar. The spring is secured from twisting or moving laterally by the lugs F F, which depend from the side bars, and engage both sides of the springs C on opposite sides of the flanges D. The carriagebars are connected together by downwardlycurved bars G G.

H H are disks having thimbles I I, and connected by a central rod, J, which passes entirely through each, and is upset at the end so as to lock them together. These disks are further connected by a series of wires, K K, which are arranged in a series about the central rod. L is a central wire which binds them together.

M M are a series of short cords or ropes made of asbestus filaments.

The spool or other lubricant-carrier is put together in the following manner: One disk, with central rod and wire securely attached, is laid fiat 011 a stand or table. Pieces of the cord, rope, or asbestus filaments are then built upon such disk, being twisted around and drawn down upon the rod and wires, as shown in Fig. 3. XVhen the spool is half filled, the central wire is secured, and the spool is then filled. The other disk is now put in place and forced toward the first disk until the rod and wires are received into the apertures prepared for them. One disk is now firmly held in a vise, and the other is turned so as to twist the wires into the position showninFig. 1. Thus the filling ofthe spool is formedinto a compact, firmly secured, twisted mass. The central rod and wires are now upset at the free end and thus clinched, and a strong. finished, cylindrical spool of asbestus filament or other lubricant-carrier is formed.

The wires could be twisted so far as to virtually form a spiral, and indeed the body of the spool could be for-med'wit-h a spiral, which would then be filled with asbestus, rope, or filament.

The use and operation of our invention are as follows: The spool, formed as shown, islaid in the boxesB B, and thus supported so as to rotate on the carriage. The whole is now introduced into the box of a car-wheel axle, so that the lower side of the spool will dip into the lubricant and the upper will touch the carwheel axle. As the axle revolves the spool is turned and carries up the oil to lubricate the wheel. The supporting-springs give the spool an elastic bearing.

We claim- 1. In a car-axle lubricator, a lubricatingspool consisting of a central rod, :1 series of wires along and of equal length therewith, and a lubricant-carrier twisted about such rod and wires.

2. In a caraxle lubricator, a lubricantspool consisting of a central rod, a disk at each end thereof, a series of wires extending from disk to disk, spirally curved about the rod, and the lubricant-carrier twisted about such rod and wires.

3. In a car-axle lubricator, a lubricantspool consisting of a centrally-cored rod and short filaments of asbestus secured to such core, and with the ends forming the surface of the spool.

4. In a car-axle lubricator, a lubricatingspool consisting of a central rod with filaments oi asbestus and supporting wires twisted about the same.

5. In a car-aXle lubricator, the combination of a lubricating-spool with its carriage, with springs which support such carriage, having flanges turned up at their sides to receive the carriage side bars, and which are perforated to receive the securing-bolt.
